We're planning a June 2010 trip. I know we'll probably be able to book our package August 2009. I've seen that there is a $200 deposit. What if I wanted to pay the package in full with credit card at the time of booking, so that my trip is "paid in full" and I can just make payment on the credit card? Is there a way to make a larger payment that the deposit when you are booking? I'm planning to do it through the website.
